You can use System.currentTimeMillis() it returns "the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC."

long time = System.currentTimeMillis();

Will do it :)

Doesn't that use the system time rather than just using GMT? If so, wouldn't this cause problems if you need the milliseconds to be standardized across more than one time zone? – Alan Nelson Jul 17 '18 at 19:31
This returns the exact same result as the accepted answer, but is much more concise. – Lambart Jul 02 '19 at 21:55

Use Calendar#getTimeInMillis:

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long time = cal.getTimeInMillis();

That is the most complicated and inefficient way of getting the GMT time I have seen. :D Under all this it has to call `System.currentTimeMillis()` which returns the time in millis for GMT. – Peter Lawrey Oct 23 '12 at 10:10
@PeterLawrey: Why do you assume OP always wants the *current* time? – João Silva Oct 23 '12 at 10:14
That is true, but if you need to store the GMT time in millis, you can use `long` for that too. – Peter Lawrey Oct 23 '12 at 11:20
Will it also handle daylight saving correctly? – sactiw Jan 11 '18 at 09:30

Use the Calendar Class to create an instance with GMT as the timezone.

From that you can get the time in milliseconds.

see below code sample.

public class TimeTest {

    public static void main(String [] args) {
        Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        System.out.println(cal.currentTimeMillis());

    }
}

Hope this helps.

For current time in millis always prefer `System.currentTimeMillis()` and also if you are using `Calendar` prefer `cal.getTimeInMillis()` instead of `cal.getTime().getTime()` – Sujay Jun 21 '13 at 09:50

Use getTime() function:

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.
